recordSizeKib

Specifies the suggested block size for a volume in a ZFS dataset, in kibibytes (KiB). Valid values are 4, 8, 16, 32, 64, 128, 256, 512, or 1024 KiB. The default is 128 KiB. We recommend using the default setting for the majority of use cases. Generally, workloads that write in fixed small or large record sizes may benefit from setting a custom record size, like database workloads (small record size) or media streaming workloads (large record size). For additional guidance on when to set a custom record size, see ZFS Record size in the Amazon FSx for OpenZFS User Guide.
